4 Claims. (Cl. 222---205) This invention relates to manually operablepaint dispensing apparatus.

The invention is more particularly concerned with improved apparatus fordispensing fluid paint in predetermined regulated volumes from areservoir into a plurality of paint receiving capsules adapted forsupply in picture craft kits.

A principal object of the invention is to provide fluid paint dispensingapparatus characterized by an elongated paint containing reservoirdisposed above a table having an elongated channel in which elongatedplatens are slidably disposed and which are adapted to removably supporta plurality of spaced paint receiving capsules, and wherein thereservoir is provided with manually operable paint flow regulatingvalves for delivery of measured volumes of paint to the respectivecapsules.

A further object of the invention is to provide for simultaneousoperation of all of the valves and wherein the valves are actuated toequal extents for the delivery of equal volumes of paint to theplurality of capsules.

A still further object of the invention is to provide for uniformvariation of the extents of valve actuation for corresponding variationof the volumes of paint delivered to the plurality of capsules.

Other objects and advantages of the invention will become apparent inthe course of the following detailed description, taken in connectionwith the accompanying drawings, wherein Bracketed Fig. 1 is a viewpartly in elevation and partly in vertical longitudinal section andshowing the essential co-operating structural features of the invention.

Bracketed Fig. 2 is an elevational view as observed from the right ofFig. 1 with the channel member and platen involved in the invention, intransverse section.

Fig. 3 is a side elevational view of the paint containing reservoirtogether with the manually operable paint dispensing mechanismoperatively associated therewith and wherein the valves involved in suchmechanism are in open paint delivery position as opposed to the closedportion thereof in Fig. 1.

Fig. 4 is a top plan view of the structure shown in Fig. 3.

'Fig. 5 is a full scale fragmental elevational view of the left-hand endof the reciprocable bar involved in said paint delivery mechanism.

Fig. 6 is an enlarged vertical sectional view of one of the valvestogether with its inlet pipe and dispensing nozzle, and wherein thevalve is in closed position.

Fig. 7 is a view corresponding to Fig. 6 but wherein the valve is inopen position.

Fig. 8 is a transverse section of the reservoir and showing a paintquantity gauge operatively associated therewith.

Referring now in detail to the drawings, 10 designates a paintcontaining reservoir which, as indicated in Fig. 8, is preferably ofcylindrical form and which, as indicated in Figs. 1, 3 and 4, is ofsubstantial length for a purpose as will later appear.

Liquid paint is admitted to the reservoir 10 from a "ice supply tank 11and through a pipe 12 which is provided with a stop clock 13.

As indicated in Fig. l, the supply tank 11 is preferably disposed aboveand adjacent one end of the reservoir 10. A vacuum tank 14 is disposedpreferably adjacent to and above the opposite end of the reservoir 10and communicates therewith through a pipe 15. v

The vacuum tank 14 is provided with a vacuum pump connecting pipe 16 andis also preferably provided with a vacuum gauge 17.

Other pipes 15 have corresponding ends thereof in communication with thevacuum tank 14 and are adapted for extension to the reservoirs of otherunits which may be arranged in tandem with the one shown. The pipes 15,15 are each provided with a shutoff cock 18.

The reservoir 10 is provided with a paint gauge in the form of a buoyantfloat 19 disposed within the reservoir and to which is rigidly connectedthe lower end of a float stem 20 which is vertically slidably disposedin a suitable bearing member 21 projecting upwardly from the reservoir.

The purpose of the vacuum tank 14 is to providea steady flow of paintfrom the supply tank 11 into the reservoir 10 and in order to provide amore positive flow of paint the tank 11 is preferably provided with agravity actuated float member 22 which includes an upwardly opening cupmember 23 whose circumferential flange bears on the inner wall of thetank and a weight member 24 supported on the base of the said cupmember. The tank is further preferably provided with a cover or lid 25.

The reservoir 10 is provided with a longitudinal series of relativelyshort pipes 26 depending from the bottom thereof and in communicationtherewith. The pipes 26 are equally spaced longitudinally or axially ofthe reservoir 10 and the lower end of each pipe 26 is rigidly connectedto a valve body 27 which is provided with a central transverse bore 28and upper and lower ducts 29 and 30 respectively whose adjacent endscommunicate with the bore 28 in off-center relation thereto, and theopposite ends of the ducts open through the upper and lower surfaces ofthe valve body 27 whereby the upper ducts 29 communicate with the pipes26 and consequently the reservoir 10. The valve bodies 27 are eachprovided with a centrally apertured fitting 31 whose aperture is incommunication with the lower end of duct 30 and a nozzle 32 depends fromeach fitting 31 and communicates with the aperture therein.

Rotatably disposed in each bore 28 is a valve 33 which is provided witha diametrical port 34.

As is indicated in Figs. 6 and 7, the valves are closed when the ports34 are inclined left-upwardly and are open when same are inclinedright-upwardly. In other words, when ports 34 are out of communicationwith ducts 29 and 30, as in Figs. 1 and 6, the valves are closed and nopaint will issue through the nozzles 32. When, on the other hand, theports 34 are in communication with the ducts 29 .and 30, as in Figs. 3and 7, the valves are open and paint is free to pass out through thenozzles 32.

The invention comprises novel means for effecting simultaneous and equalmovement of the valves 33 and such in a preferred structural embodimentthereof comprises an elongated bar 35 whose opposite ends are slidablyor reciprocably supported in brackets 36 which are rigidly secured toopposite ends of the reservoir 10 and the bar 35 is provided with aplurality of depending fingers 37 each of which is provided with adownwardly opening slot 38. The valves 33 are each provided with ahorizontal stem 39 and a lever arm 40 projects radially from each stemadjacent the outer end thereof.

The lever arms 40 are provided with terminal right angular portions 41which are received within the slots 38.

With this arrangement sliding movement of the bar 35 moves the valves 33to open and closed positions as in Figs. 7 and 6 respectively.

One end of the bar 35 is provided with a hand engageable handle 42 formanual manipulation of the bar and the resulting movement of the valves.

It is to be observed that in the dispensing of. paint from the nozzles32, the bar 35 needs to be moved to, the position of Fig. 3 for aninstant only and then moved back to its valve closing position of Fig.1, since an instant only is required to dispense a relatively smallpredetermined volume of the paint. Proper operation of the bar becomeshighly efiicient as a result of-experienceby an operator.

In cases where smaller volumes of paint are required to be dispensed,the dispensing stroke ofthe bar 35 may be varied by placing a stop pinin one of the apertures 43 in the end of the bar opposite the handle 42and which pin will engage the adjacent bracket 36 to limit dispensingmovement of the bar.

The dispensed paint is adapted to be supplied to small capsules 44 whichare removably disposed in upwardly opening pockets 45 formed in anelongated platen 46 which is longitudinally slidably disposed in aguidechannel 47 in the upper face of a channel member 48 rigidly securedto the upper face of a suitable table or bench 49.

The capsule receiving pockets '45 are longitudinally spaced in keepingwith the longitudinal spacing of the paint delivering nozzles 32 wherebywhen a capsule supplied platen 46 is slid into the channel 47 thecapsules may readily be positioned immediately below the nozzles forsimultaneously receiving equal volumes of paint therefrom.

As indicated in Fig. 1, several platens may be in sliding positionwhereby when one is slid into capsule filling position, the one inadvance thereof whose capsules have already been filled is pushed out offilling position.

While We have disclosed our invention in accordance with a singlespecific structural embodiment thereof, such is to be considered asillustrative only, and not restrictive, the scope of the invention beingdefined in the sub-joined claims- What We claim and desire to secure byU. S. Letters Patent is:
